ii

When installing, operating, or performing maintenance on this equipment, the following

safety precautions should always be taken into account in order to reduce the risk of fire,

electric shock, and personal injury.

Carefully read the safety instructions below before using this product.

• Observe all of the warning and instruction signs distinctively marked on the product.

• Before performing system installations, please consult the User’s Manual provided

with this product.

• Do not place this product on an uneven or weak surface (unstable cart, stand, table,

ect.) that might induce the product to fall and sustain serious damage.

• Install only the equipment or device identified in the User’s Manual. Deploying other

equipment or device with this motherboard could invoke improper connection of

circuitry that leads to fire or personal injury.

• This product should only be operated with the type of power source indicated on the

marked label. If you are questionable about which type of power supply is used in your

area, consult your dealer or local Power Company.

• Disconnect the power supply module before removing power from the system.

• Unplug this product from the wall outlet before cleaning. Use a damp cloth for

cleaning. Do not use liquid cleaners or aerosol cleaners.

• Do not use this product near a water source, including faucet and lavatory.

• Never spill liquids of any kind on this product.

• Never shove objects of any kind into this product’s open slots, as they may touch

dangerous voltage points or short out parts and could result in fire or electric shock.

• Do not block or cover slots and openings in this unit, as they were made for ventilation

and prevent this unit from overheating. Do not place this product in a built-in

installation unless proper ventilation is available.

• Do not disassemble this product. This product should only be taken apart by trained

personnel. Opening or removing covers and circuit boards may expose you to electric

shock or other risks. Incorrect reassembly can also cause electric shock when the

unit is subsequently used.

• Risk of explosion is possible if battery is replaced with an incompatible type. Dispose

of used batteries accordingly.

• This product is equipped with a three-wire grounding type plug, a plug with a third

(grounding) pin. As a safety feature, this plug is intended to fit only into a grounding

type power outlet. If you are unable to insert the plug into the outlet, contact your

electrician to replace the outlet. Do not remove the grounding type plug or use a

3-Prong To 2-Prong Adapter to circumvent the safety feature; doing so may result in

electric shock and/or damage to this product.

Chapter 2. Hardware Setup

 Attach the heat sink onto the CPU carrier. Hook the corners of the CPU carrier to the

back side of the heat sink.

 Install the assembled heat sink and CPU carrier onto the CPU socket. Please use a T-30

torque driver tighten the the nuts in the four corners of the heat sink labeled in the order

1  2  3  4.

CAUTION

Failure to tighten the heat sink screws in the specified order may cause damage to the

processor socket assembly. Heat sink screws is recommended to be tightened to 8 in-

lbs torque, but can be tightened to 12 in-lbs torque according to the indicated order on

the top of the heatsink label.
